Raising a budding architect? Foster their love for construction by stocking up on building toys. These types of construction toys come in a variety of forms—from blocks to magnetic sets and more—but they all share the same, basic qualities. They inspire your little one to get creative and use their hands in a constructive manner during play. The best building toys for kids are durable, easy to manipulate, and fun, of course—and we’ve uncovered the top options on the market today. Find out more about the benefits below, then browse our favorite building toys, from wooden classics to STEM and Montessori-inspired options.

Benefits of Building Toys

Building and construction toys aren’t just fun and games (though, that’s important, too!); they offer several developmental and educational benefits, as well. Building toys encourage open-ended play, whereby children are free to create and imagine on their own. Research has shown that this type of play is extremely beneficial to children and their development. “I have discovered links between open-ended, self-chosen pretend play and block building and language, social skills and early mathematical thinking,” explains Jeffrey Trawick-Smith, EdD, a writer and retired professor of early childhood education at Eastern Connecticut State University.

Trawick-Smith also revealed that, in a 10-year toy study conducted by the Center for Early Childhood Education at Eastern Connecticut State University, building toys were some of the highest-rated toys for 3- and 4-year-old children. “We found that construction toys—hardwood blocks, Legos, etc.—inspired the highest quality play using a measure we developed,” Trawick-Smith shares.

Building toys also introduce kids to basic math and science principles, helping them develop their gross, fine motor and language skills, while fostering team-building, creativity and problem-solving. “Building play involves much symbolic thought—the same kind of thinking needed for language and reading,” Trawick-Smith explains. He also highlighted the connection between block play and early math skills. “Children who build more complex block structures over the course of a year show greater gains in a measure of their understanding of number, space and measurement,” he adds. Building toys are so good at providing quality play opportunities for children that Trawick-Smith encourages all families, if they can afford it, to invest in a set of wooden blocks.

While building toys are a wonderful resource for kids, it’s important that the set you buy is age-appropriate and safe. For toddlers under the age of 3, steer clear of construction toys with small pieces that can fit inside your little one’s mouth, as they could pose a choking risk.
